WIRING SYSTEM.

Application filed April 6. 1921. Serial No. 459,103.

To all whom ill-may concern:

Be-it known thatI, Jomv W. HILL, a citizen of-the'United States, and aresident of Salt'LakeCity," in the county of Salt Lake andState of Utah,have invented certain new and useful Im rovements in Wiring Systems,=0fwhich the'following is aspecification.

This invention relates to a wiring system adaptedfor-usein-connectionwith the transmitting circuit of wirelesstelegraphy.

lt is awell'known fact that a radio transmitter produoes a broadwave-length. This is-provenby tuning the wave length of maximum"energyfrom a transmitting station until a=-p'oint is' found where the signalis maximum-i" On each side of this position of adjustment, the energywill get weaker, but still the-signal wil'l'be audible. The portionof'the 'wave' on each side of its maximum point is of course a loss ofenergy, and furthermore causes interference with other re- By experimentI havefound that a broad wave isproduced by a transmittingapparatus'when the wiring thereof is unequal, that is to say, the wiringof especially the capacityunitsi in said circuit is unequal from acommon point.

It is the ob'ect of this invention to provide a wiring sy steih by whichthese units may be Wired so that each will be disposed at an equaldistance from a common point in the circuit with which they areassociated, or the transmitter circuit as before referred to.

The invention is illustrated by way of comparison and example in theaccompanying drawings, in which- Figure 1 is a diagrammatic view showingthe connection of a plurality of condenser plates, so that each plate isan unequal distance from a common point,

Figure 2 is a diagrammatic view illustrating the connection of a numberof condensers, divisible into pairs, and each of the condensersconnected an equal distance from a given point in accordance with myinvention Figure 3 is a diagram of a wireless transmitting circuit inwhich audion bulbs are connected an unequal distance from a given point,

Figure 1 shows a similar circuit as shown in Figure 3 and connecting theaudion bulbs in accordance with my invention,

Figure 5 is a wiring diagram showing the connection of an odd number ofaudion bulbs in accordance with my invention, and

Figure 6 is a sectional diagrammatic view showin the manner in which thedifferent units 0 each of the audion bulbs are connected.

Referring to the drawings, and particularly to Figure l, 10 indicates aplurality of condenser plates of the same polarity, and 11 a likenumberofplates of the opposite polarity. The plates 10 are each connected to awire 12 while the plates 11 are likewise connected to a wire 13. It isan obvious fact that if the wires 12 and 13 were connected with thetransmitter circuit of the radio apparatus, the pulsations from eachplate of the condenser would vary in length, that is to say, the platesnearest the points 14' of each ot the connecting wires would give offthe sharpest form of wave, while the succeeding plates 1 would givesuccessively broader forms of waves.

Referring to Figure 2, a number of condenser plates are shown, but of aneven number. This must be the case in order to carry out my .invention.Each pair of plates of similar polarityis connected by a wire 16, afterwhich the adjacent pairs so formed by the connecting wires 16 areconnected by a wire 17. The wires 17 connect with the wires 16 at acentral point, as shown. In this instance. as may be observed, there aretwo wires 1.7 and these two wires are connected at a central point witha wire 18. The wire 18 at its middle at 19 forms a given point which isof equal distance from either of the plates 16 with which it isconnected. This same manner of wiring is carried out for the condenserplates of opposite polarity as shown, and from the points 19 the Wiremay be led and connected with the opposite sides of the oscillating coilin the usual man ner.

Referring to Figure 3, 20 indicates generally a number of audion bulbswhich in this instance, is three, and of which bulbs 21 indicate thefilament, 22 the grid, and 23 the plate. The plates are each led to awire 24 which in turn leads to one side of the oscillating coil 25. Thegrids are likewise each conncctcd with a wire 26 and the filaments withthe wire 27. In this instance, the filament. grid and plate of eachaudion bulb is of unequal distance from a given point in wires 25and 27,which primaril constitute 'thecirbuit of 'the foscillator 25. Such anarrangement of wiring produces the broad wave which is given off by theaerial indicated at 28.

In Figure 4 I have shown four audion bulbs 20 which are connected inaccordance with my invention. Each pair of grids 33 is connected by awire 29 and the pairs so formed are in turnconnccted by a wire 30, saidwire'30 joiningor-being connected to Wires 2% at a central pointthereof. The adjacent file ments 21 are in turn connected together bywires 31 and the'pairs so formed are connected'by a wire 32, this wire32 being in turn connected from a central point to one side of theoscillator circuit. The plates of adjacent bulbs are connected by a wire33 and the pairs so formed are in turn connected by a wire 34, said wire34'being then connected at a central point to the other side of theoscillator circuit. This arrangement dispm each of the elements which goto make upth'e 'audi'on bulbs an equal distance from a given point, andthe oscillator circuit will produce and enable a narrow or sharp wave tobe given off at the antenna 28 when send @efrrihg to Figure 5, 35indicates gener: ally aiiumber of audion bulbs which have been arrangedin circular formation, and it is to be understood that they areconnected in a receiving or transmitting circuit, such as shown inFigures 3 and 4. The audion bulbs or units in this instance however areodd in number, and the wire arrangement which I have heretoforedescribed would not be permissible. instead the grid 36 of each bulb isled to a'common point as at 37,

shown in Figure 6. Likewise the filaments 3:17 and the plates 38fare-ledpoints 39 and 40, respectively, as shown in Figure 6. A airingarrangement of this kind for an odd numberoi' units will produce thesame result with respect to the wave form transmitted as that describedfor Figure 4.

While I. have shown and described my apparatus when used in connectionwith a transmitting wireless apparatus, it is .to be underlsood that thesame connection can be made use of in the receiving apparatus withequaliy good results, or it can be used when several units are wired inthe aerial circuit.

1. The method of connectinga plurality of electrical units in a circuitwhich are divisible into pairs an equal distance fromag i en point,which consists in connectingeachpjair, then connecting adjacent pairs,and fthen connecting adjacent pairs formed by said last mentionedconnection and, repeating such connection of adjacentpairs until but onewire is the resultant, the central point of this Wire being the pointcommon to all the units.

2. The method of connecting a'plurality of electrical units, whichconsists in connecting the units in pairs and then connecting said pairsto a common point, said point being of an equal distance from each unit.

3. The method of connecting an even number of electrical units, whichconsists in connecting said units in pairs and then connecting the pairsso formed to acommon point which is an equal distance from each unit.
